gulp task with gulp-sync emit error while finishing first task

[Obooman]

task1 works,while before run task2 it emit an error says 'cb is not a function',run task2 alone doesn't show any warn or error.

[11:11:58] Finished 'task1' after 208 μs
[11:11:58] 'sync group0:0' errored after 1.93 ms
[11:11:58] TypeError: cb is not a function

gulpfile scripts as below:

gulp.task('default',gulpsync.sync(['task1','task2']))

there's no any 'cb' keyword in my gulpfile.

node -v: v4.2.1
gulp -v: version 3.9.0

I'm sorry for my late reply.

I used cb keyword in gulp-sync code.
probably, the error was from there.

I'm not sure but maybe it will be fixed. see below link.
